One can't use the name for this purpose, it's not reliable. When saving
the frame configuration one stores the ID of the window associated with
each frame along with its geometry. When restoring the configuration
one must make a new call to `windows' with '%n %i' in the argument to
get the window number corresponding to the saved ID. The ID is unique
to each window and doesn't change. But it does can happen that the
window just don't exist anymore....
